“He was standing less than a metre away from the dead man’s head. He had a professional camera with a zoom. I thought that it was quick for a journalist to get on to the scene,” one witness told daily Svenska Dagbladet (SvD).

After taking the man’s picture, the photographer vanished from the scene.

The second eye-witness, who was closer to Abdulwahab and the unidentified photographer, told the paper that the man gave him an eerie feeling.

“To most he was just a lucky photographer who stumbled upon the incident. But to me, he was something more. It was as if he had been waiting for the blast,” he said to the paper.

Terror experts told the newspaper such occurrences are not that unusual. Rather, through previous experiences with suicide bombings, experts have seen that there are often those who follow the bomber, within an appropriate distance from the blast.

“This could be because of one of three reasons: there is not complete trust in the bomber himself, they want to be able to show the world propaganda material of how well they have done and finally to learn from the experience before sending out the next bomber,” SvD’s terror source said.

The fact that the photos, which could have been sold for at least 100,000 kronor ($14,835), have never been published also raises questions and points to the snapper having been connected to the attempt, according to the paper.
